Penguin Finance Will Integrate Chainlink VRF to Secure the Penguin Arena Gamified dApp

We’re excited to announce that Penguin Finance — the leading gamified DeFi hub on Avalanche — will integrate Chainlink Verifiable Random Function (VRF) on the Avalanche blockchain. By integrating Chainlink’s industry-leading decentralized oracle network, we can obtain access to a tamper-proof and auditable source of randomness needed to determine the victors of the Penguin Arena and distribute rewards accordingly. Ultimately this creates a more exciting, transparent, and fraud-proof user experience, as users can enjoy ultra-fast settlement on their actions with peace of mind.

Penguin Finance is an innovative DeFi project on the Avalanche Network. In the last five months, PeFi has managed to build a fully-fledged ecosystem; leveraging on near-instant transactions, paramount levels of decentralization, and low gas fees. Currently, the project offers yield-aggregation, farming, staking, fundraising, and gaming dApps that can’t be found on any other blockchain. The upcoming Penguin Arena will be ground-breaking, marking the first interactive NFT game ever built on Avalanche. By incorporating programmatically, randomly generated Penguin NFTs in a PvP gaming dApp, this DeFi project plans to make history.

In order to securely and fairly determine the winners within the Penguin Arena game, we need access to a secure random number generator (RNG) that any user could independently audit. However, RNG solutions for smart contracts require several security considerations to prevent manipulation and ensure system integrity. For instance, RNG solutions using on-chain data like block hashes can be exploited by blockchain miners, while off-chain RNG solutions like traditional data providers are opaque and don’t provide users with definitive proof about the integrity of the process.

After reviewing various solutions, we selected Chainlink VRF because it’s based on cutting-edge academic research, supported by Chainlink’s time-tested oracle infrastructure, and...
